如何显示最近启动的 10 个进程

  • 772

我正在尝试将输出通过管道传输ps -ax -o pid,lstart到 an中awk并使用它，或者尝试使用sort.

的输出ps -ax -o pid,lstart类似于：

       PID         STARTED
    1 Tue Feb  4 23:10:00 2020
    2 Tue Feb  4 23:10:00 2020
    3 Tue Feb  4 23:10:00 2020
    4 Tue Feb  4 23:10:00 2020
    6 Tue Feb  4 23:10:00 2020
    8 Tue Feb  4 23:10:00 2020
    9 Tue Feb  4 23:10:00 2020
   10 Tue Feb  4 23:10:00 2020
   11 Tue Feb  4 23:10:00 2020
   12 Tue Feb  4 23:10:00 2020
   14 Tue Feb  4 23:10:00 2020
   15 Tue Feb  4 23:10:00 2020
   16 Tue Feb  4 23:10:00 2020
   17 Tue Feb  4 23:10:00 2020
   18 Tue Feb  4 23:10:00 2020
   20 Tue Feb  4 23:10:00 2020

这使工作变得更加困难，因为我必须先按天排序，然后是一小时、一分钟和一秒……

text-editor sort ps

    您可以etimes用作代理，lstart以秒为单位为您提供一个允许简单数字排序的值。

    $ ps -eoetimes=,pid=,lstart= | sort -rnk1,1 | tail -10

    来自man ps：

       etimes      ELAPSED   elapsed time since the process was started, in
                         seconds.

   lstart      STARTED   time the command started.  See also
                         bsdstart, start, start_time, and stime.
